GB/T 7341.5-2018 Electroacoustics—Audiometric equipment—Part 5:Instruments for the measurement of aural acoustic impedance/admittance

Scope

This part of GB/T 7341 specifies the performance of three types of ear acoustic impedance/admittance measuring instruments and the facilities provided for these instruments, as well as the test methods used for acceptance testing and guiding routine calibration.
This part is applicable to instruments used to measure acoustic impedance/admittance in the human external ear canal using the specified pure tone detection signals, and also to instruments of this type using other detection signals.
This part aims to ensure the consistency of all instruments that comply with this part under comparable test conditions. This part does not intend to restrict the development or introduction of new features, nor does it hinder the innovation of technical methods.
